PSR 05-01352-22 Air Injection Block Off Plate Black Suzuki

The PSR 05-01352-22 Air Injection Block Off Plate allows elimination of the factory air injection system on Suzuki motorcycles. This CNC-machined aluminum block off plate is designed for riders who have modified their fuel mapping or installed aftermarket exhaust systems on their sportbikes.

Key Features:

• CNC-machined from high-grade aluminum for precise fit and reliable seal
• Safely blocks and seals off air injection ports to prevent backfiring
• Enables accurate air-to-fuel ratio measurement on the dyno
• Allows removal of excess equipment weight from valves and hoses
• Essential for motorcycles with O2 sensors and Power Commander tuning systems
• Black anodized finish for a clean, professional appearance

Eliminating the air injection system prevents the introduction of fresh air into the exhaust stream, which can cause annoying and potentially damaging backfires when combined with modified fuel mapping. This is particularly important for bikes equipped with aftermarket tuning devices like the Dynojet Power Commander, where additional oxygen can skew sensor readings and prevent accurate tuning.
